Abstract

The invention discloses a uvioresistant and anti-static chemical fiber yarn and a preparation method thereof. The preparation method comprises the following steps: at first, loading a plurality of silver ions on a modified metal organic framework, blending with spinning solution to obtain chemical fiber, grafting AESO outside the chemical fiber, and carrying out copolymerization on modified microspheres to obtain a chemical fiber inner layer; manufacturing modified microspheres by taking methyl methacrylate as a wall material and taking hexadecane, plant essence and beta-1,4-polyglucosamine ascore materials; and adding an ultraviolet absorbent and dopamine in absorbing film slurry, and soaking the fiber inner layer in the absorbing film slurry for 20-30 hours, and taking the fiber inner layer out. Through synergistic effect of the modified metal organic framework, the modified microspheres, the absorbing film slurry and the like, the problems about hydroscopicity, antibacterial property, fragrance retention property and washability of common chemical fiber fabric are improved to a greater degree, and higher practicality is improved.

Description

technical field [0001] The invention relates to the technical field of textile yarns, in particular to an anti-ultraviolet and anti-static chemical fiber yarn and a preparation method thereof. Background technique [0002] Clothing has the function of protecting the human body and decoration, and is an indispensable item in people's daily life; when people wear clothes, friction between the body and the clothes will inevitably occur to generate static electricity. Compared with natural cotton and linen fabrics, the mass-produced chemical fiber fabrics are poor in hygroscopicity and insulation, and it is very easy to generate static electricity in dry weather; static electricity will cause people to feel numbness, affect emotions, and make people become restless; Static electricity will also make chemical fiber cloth stick to the skin, absorb dust, affect the wearing experience, and make people feel awkward in public places; with the popularity of micro electronic devices, st...
